Part 1: T0 versus T90 physiology

Figure 1

Figure 1. True mean (+/- SE) physiology of T0 coral fragments (one per colony; n = 8-14) denoted by black cross with (A) individual colony physiology denoted by coloured shape or (B) native reef environment.

Figure 2

Figure 2. True mean (+/- SE) T0 and T90 coral fragment physiology of (a) S. siderea, (b) P. strigosa, (c) P. astreoides, and (d) U. tenuifolia with individual coral fragment physiology denoted by points. T0 corals are represented by green stars. Blue denotes 28C, red denotes 31C, and shape corresponds to pCO2 treatment conditions of T90 fragments.

Figure 3. Modelled 95% confidence interval of (a) S. siderea, (b) P. strigosa, (c) P. astreoides, and (d) U. tenuifolia physiology with individual coral fragment physiology denoted by points. Blue denotes 28C and red denotes 31C, with pCO2 treatment along the x axis.

Notes:

  • Red best predicts denisty, but colour overall predicts density better than chlorophyll in SSID
  • Red best predicts chlorophyll, but any channel (with the exception of blue) predicts both density and chlorophyll in PSTRs
  • Colour intensity predicts chlorophyll, but not density in PAST
  • No colour analysis predicts UTEN bleaching
